ABSTRACT. Recent advances in the nomenclature and improvements in the description of morphological characters have made possible to better understand the variability of taxa of the genus Orthomus Chaudoir, 1838, and to develop more accurate keys of Ibero Maghrebian species, whose information was to date scattered in different publications. A brief review of key morphological characters of these species based on the study of the collections of the University of Murcia and the National Museum of Natural Sciences of Madrid, has allowed to develop a comprehensive key to these taxa, what may help to check beetles of Orthomus. Likewise, the value of morphological and geographic characters is discussed on evolutionary grounds, as a basic knowledge for future phylogenetic studies of particular lineages.

KEY WORDS. Coleoptera, Carabidae, Pterostichini, Orthomus, taxonomy, species key, new status, Iberian Peninsula, Morocco.
